Ubuntu 20.04 LTS does not shutdown on HP Desktop

fr flag

When shutting down screen goes black but power light does not go off. I even left it overnight and the power light remained on. Output of Journalctl sudo journalctl -b -1 -e

So far I haven't found a solution. I submitted a bug report.

If the HP desktop that you are using is similar to the All-in-One machines that I've supported in the past, then you may need to make a slight modification to your Grub file to disable ACPI warnings, which can keep a computer active.

Here's how you can do it:

  1. Open a Terminal (if it's not already open)
  2. Edit your /etc/default/grub file with sudo:
    sudo {editor of choice} /etc/default/grub
    
    Note: Be sure to replace {editor of choice} with your editor of choice.
  3. Find the line that starts GRUB_CMDLINE_LINUX_DEFAULT and add acpi=off to the end of the line, but inside the quotes. For example:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"
    
  4. Save the file and exit
  5. Update Grub:
    sudo update-grub 
    
    Note: This step is important. If you skip it, then the change will not be applied no matter how many times you reboot.
  6. Restart your computer

Hopefully this allows your rest-deprived HP to shut down properly

Thank you for the suggestion, unfortunately this did not fix the problem. I edited the file and updated grub as you suggested. Can I supply any information to you that might help find and fix the issue?

I just noticed after the above change my sound stopped working. I removed the edit, updated grub and my sound came back after rebooting.

It didn't work. Ubuntu 20.04.3 LTS, Kernal version 5.13.0-27-generic, GNOME version 3.36.8. Also, I'm pretty sure this occurred with the firmware update that came with the usual Linux updates last week.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
